Who doesn't like to celebrate the 4th of July with a pitcher of ice-cold margaritas? Unfortunately, with seven calories per gram, alcohol is undeniably not figure-friendly. Neither is all that other stuff mixed in with the tequila. One shot of 80-proof tequila has about 100 calories, and there’s a good chance that there's more than one shot in your margarita (try two, three or even four). Already, you’re nursing about 300 calories of tequila; and that doesn’t even include the triple sec and sweet and sour, which can quickly add another 200 calories. One seemingly innocent 16-ounce margarita can end up costing you 500-600 calories… and that’s just what you’re sipping through your straw. Let’s not forget about all that party food! Burgers, chips and dips, hot dogs, wings, potato salad, and more. You could be taking in 2,000 calories at your Independence Day barbecue alone (and remember, that doesn’t include breakfast or lunch). And while one day of reckless eating won’t put the final nail in your diet coffin, it will set you back if you overdo it. So just keep moderation in mind. Don’t skip the party… but do skip the margarita, or at least vow to stick with just one.
